Query below lists check constraints defined in the database ordered by constraint name.

Check this query to see them organized by table.

Query

select con.[name] as constraint_name,
    schema_name(t.schema_id) + '.' + t.[name]  as [table],
    col.[name] as column_name,
    con.[definition],
    case when con.is_disabled = 0 
        then 'Active' 
        else 'Disabled' 
        end as [status]
from sys.check_constraints con
    left outer join sys.objects t
        on con.parent_object_id = t.object_id
    left outer join sys.all_columns col
        on con.parent_column_id = col.column_id
        and con.parent_object_id = col.object_id
order by con.name

Columns

• constraint_name - name of the constraint in the database
• table - schema and table name constraint is defined for
• column_name - name of the column for column-level check constraints, null for table-level check constraints
• definition - SQL expression that defines this check constraint
• status - constraint status
  • 'Active' if constraint is active,
  • 'Disabled' for disabled constraints

Rows

• One row represents one check constraint
• Scope of rows: query returns all check constraints in the database
• Ordered by constraint name
